Abstract

[reaction: see text] Novel D-pi-A NLO-phores based on the 1,3-dithiol-2-ylidene donor and the thiobarbituric acceptor moieties have been prepared. Modification of the length and rigidity of the pi-spacer allows the first systematic study of the second-order nonlinear optical properties of doubly proaromatic merocyanines. The pi-electron donor efficiency of the 1,3-dithiol-2-ylidene group is superior to that of the tetrathiafulvalenyl group.
